Answer:
Option-A
Step-by-step explanation:
The light waves travel in the form of electromagnetic waves in one of the two planes. The magnetic waves are perpendicular to the electric waves. The waves which travel in more than one plane is known as unpolarized light like sun rays.
The polarizing filter converts the unpolarized light to the polarized light by allowing the light waves to flow only in one plane. When the polarizing filter is placed vertically, the vertical filter allows the vertical light rays to pass through it.
Thus, Option-A is correct.
